Because the tools created for censorship for the good cause are too dangerous to exist
Governments quickly realize that they cannot effectively block websites in foreign jurisdictions. The only way to achieve this is to tell local ISPs which subnets to block, and fine them if they disobey. When this automation is in place, the government can block any website in a matter of hours, no matter where it is located
Comparing it to the physical thing is not fair. Murder is slow, and for mass murder at least there are people who will have to agree and do it. Compare it to automatically blocking a website after a button is pressed
And murder is transparent, you cannot murder many people without a public reaction. With the internet though... They can block thousands of IPS and no one will know. And you cannot access the database of the blocked resources because, who are you, a pedophile?
I have a feeling I cannot explain how painful it is to live in a country destroying the internet. I wanted to leave the Russia even before the war because of that. Now I am extremely allergic to any government's censorship attempts
